According to the production of timber harvesting,[link widoczny dla zalogowanych], the local food system and the use of wood from the cutting area will be transported to the final yards or material sent to the user's transport distance,[link widoczny dla zalogowanych], calculate the cost of logging and wood transport. Can be confirmed by the actual production from the cutting area of wood delivered to the user directly to the hands of the least total cost. The model can also be used for other projects.
